摘要: 通过对荆南长江干堤李家花园堤段减压井基础砂矿化和井水水质进行分析,得出李家花园堤段减压井井水中含有较高的铁及铁化合物是导致减压井化学淤堵的主要原因。国际国内生活饮用水水质标准规定饮用水中铁含量不能超过0.3mg/L,降低减压井井水中铁含量是利用已建堤防减压井解决沿岸农村饮用水问题和减少减压井化学淤堵保障堤防安全的关键。针对减压井井水中铁含量过高的问题,在前人研究成果的基础上,提出了利用物理法、生物法等方法对李家花园堤段减压井井水进行净化处理。此研究对解决沿堤农村饮用水问题及保障堤防安全具有重要意义。

Abstract: By analyzing the foundation sand and water quality of relief wells at Lijia garden  segment of Yangtze Rive main dike in the south of Jingzhou, it’s found that large content of iron and iron compounds in  water is the main cause of chemical clogging of relief well. According to international and domestic drinking water quality standards, the iron content in drinking water should not exceed 0.3 mg/l. It's crucial to reduce iron content in the water to solve rural drinking water problem along the dike and to reduce chemical clogging and protect dike safety. Based on previous studies, physical and biological methods including microfiltration, aeration, and enzyme purification are proposed to purify the water in relief well. This research is of great value for dike safety and rural drinking water along the dike.

Key words: relief well, drinking water, water quality standard, chemical clogging
